Acidifying oceans could dramatically impact the world's squid species, according to a new study led by Woods Hole Oceanographic Institution (WHOI) researchers and soon to be published in the journal PLOS ONE. Because squid are both ecologically and commercially important, that impact may have far-reaching effects on the ocean environment and coastal economies, the researchers report.

"Squid are at the center of the ocean ecosystem—nearly all animals are eating or eaten by squid," says WHOI biologist T. Aran Mooney, a co-author of the study. "So if anything happens to these guys, it has repercussions down the food chain and up the food chain.".
